See your eye doctor: For your symptoms of floaters you should see your eye doctor right away to see if it's the sign of a serious problem. As for your other symptoms, they should warrant some further testing.
I believe that it is correct to say that RNA is not replicated, but reproduced. DNA, what I know currently, is the only one that replicates itself.   Plus, to my knowledge, you don't need to copy a RNA strand.
The polymerase starts replication at the 3'-end of the primer, and copies the opposite strand. In vivo DNA replication utilizes short strands of RNA called RNA primers to initiate DNA synthesis on both the leading and lagging strands â DNA primers are not seen in vivo in humans. These RNA primers can be made de novo.
